SPECIFICATION forming part of Letters Patent No. 791,459, dated June 6,1,905.

' Application filed February 11, 1904- Serial No. 193,101-

To ctZZ whom it may concern:

Be it known that we, WILLIAM EBNETHER' and J OSEPH A. LAUGHEAD,residents of J ean- 'nette, in the county of Westmoreland and simple,and effective machine for the purpose, as well as one which practicaluse has roven will finish bottle-necks rapidly, erectly, and uniformlywithout the emp oyment of any skilled labor. 1

Our invention consists, generally stated, in'

the novel arrangement, construction, and combination of parts, ashereinafter more specifically set forth and described, and partlcularlypointed out in the claims.

To enable others skilled in the art t which our invention appertains toconstruct and use our improved machine for finishing bottle-necks, wewill describe the same more fully, referring to the accompanyingdrawings, in which-- Figure 1 is a lan view of our im roved machine formaliing bottle-necks, s owing the same in its normal position. Fig. 2 isa side elevation of the same, showing the manner of finishing abottle-neck thereon. Y Fig. 3 is an enlarged face view of thehead-plate, showing parts of the plug and jaws in section. Fig. 4 is anenlarged end view of one of the jaws. Fig. 5 is an enlarged sectionalview of the front end of the shaft and showing in full lines the devicefor holding and adjusting the plug therein. Fig. 6 is an enlarged detailview, partly in section, of another form of attaching the strips or barsof the mandrel or lug to the shaft. Figs. 7 and 8 are views 0' anotherform of plug. Fig. 9 is a sectional view of another form of holding thedies.

Like symbols of reference herein indicate like parts in each of thefigures of the draw ings.

As illustrated in the drawings, 1 represents a frame on which are thebearings 2 for the shaft 3, and on this shaft is mounted a pulley 4 forrevolving said shaft by means of a belt (not shown) in the ordinarymanner. A head 5 is formed or secured on said shaft 3, and extending outfrom said head is a guiding-plate 6, which is seated on each side, as at7, for the reception of the jaws 8- 8, and these jaws are pivoted at 9in a supportingplate 10, extending out from the head 5. The rear orinner ends 8 of the jaws 8 8 are provided with the inclined or beveledfaces 1 1v on their inner faces 12, with which a coneclutch 13 isadapted toengage, this clutch being slidably mounted on the shaft 3 by afeather 13 and being provided with a groove 14 around the same in therear of its beveled engaging face 15 for the reception of a yoke 16, towhich an operating lever or bar 17 is attached for moving the clutchalong said shaft 3.

Springs 18'are placed between the head 5 and the innerfaces 12 of thejaws 8 8for holding the front or outer ends 12 of said jaws 8 8 normallyoutward, and dies 19 for giving the exterior shape to the bottle-neckare secured in dovetailed recesses 20 on the inner faces 12 and at theouter ends 12 of said jaws 8 8 by means of the set-screws 21.

Between the dies 19 on the jaws 8 8 is themandrel or plug 22, which isof the usual cylindrical and ta cred-point form, and such .plug isdivided ongitudinally into two sections 23. Extending backward from therear end face 24 of said plug 22, and from each section 23 thereof, arethe bars 25 25', and these bars are curved outwardly, as at 26, in orderto formthe s ace 27 between them. The rear ends 28 0' said bars 25 25are secured to a screw-plug 29 by means of a bolt 30, passing through ahead 29 on the same, an such screw-plug 29 is screwed into a threadedseat 31 in the front end of the shaft 3 by means of the threaded portion32 thereon for holding and ad'usting the plug 22. The jaw 8 is connecteto the bar 25 by means of the rod 33, which passes loosely through thejaw 8 and bars 25 25 and is provided with the nuts 34 at each endthereof for bearing against the outer faces of the jaws 8 and bar 25 inthe normal position of said jaws, while the jaw 8 is connected to thebar 25 by means of the rod 33, which passes loosely through the aw 8 andbars 25 25 and is provided with nuts 34 at each end thereof for bearingagainst the outer faces of the jaws 8 and bars 25 in the normal positionof said jaws. The rods 33 33 have spiral springs 34 around the same andinterposed between and against the bars 25 25, so as to be confinedwithin the space 27, and such springs 35 act to cushion the bars 25 25and allow such bars to have an outward tendency and with them the plug22 when in operation.

The bars 25 25 on the plug 22 pass through an enlarged opening 35,formed in a headplate 35, which is adapted to rest against the rear endface 24 of said plug and is rovided with rods 36, extending out from t esame, which pass loosely through openings 36 in the aws 8 8 and back ofthe dies 19 therein and have nuts 36 engaging with the ends thereof andwith the outer faces of said jaws. The use and operation of our improvedmachine for finishing bottle-necks is as follows: When power is ap liedby means of the belt (not shown) to t 16 pulley 4 on the shaft 3, thesaid shaft, aws 8 8, plug 22, and their connecting parts are allcontinuously revolved with said pulley, and when it is desired to finisha bottle-neck, as shown in Fig. 2, the unfinished neck of the bottle isinserted between the jaws 8 8 over the plug 22 and against thehead-plate 35 in the rear of said p ug. At about the same time as thisis bemg done the operator pulls the lever 17, connecting the yoke 16 onthe cone-clutch 13 on the shaft 3, and so moves said clutch forwardalong said shaft, which allows the beveled engaging face 15 on saidclutch 13 to engage the beveled faces 11 on the jaws 8 8, therebyforcing outwardly the rear ends 8 of said jaws, so that the front ends12 of said jaws will be forced inwardly by reason of the pivoting ofsaid aws at 9. When the front ends 12 of said jaws 8 8 are thus forcedinwardly, the springs 18 between said jaws and the head 5 are compressedand the dies 19 come in contact with the glass in the unfinishedbottleneck and against the head-plate 35, so that as the aws 8 8 andplug 22 are revolved the neck will be finished between the dies 19, andduring this movement of the jaws the sections 23 of the plug 22 will beforced outwardly to form the interior and assist in the finishing of theneck by the releasing of the compression on the spiral springs 34" inthe space 27 on the bars 33 33 and bearing against the bars 25 25. Afterthe neck of the bottle has been thus finished and it is desired toremove the same all that is necessary is to push back the lever 17 andwith it the yoke 16, fitting around the cone-clutch 13, thereby allowingsaid clutch to be forced back along the shaft 3, so that its beveledface 15 will be freed from the beveled faces 11 on the jaws 8 8 andpermitting the springs 1.8 to throw out the front ends 12 of the pivotedjaws 8 8. hen the ends 12 of the pivoted jaws 8 8 are thus thrown out oropen, the sections 23 of the plug 22 are brought together by the rods 3333, thereby compressing the springs 34 around said rods and within thespace 27 be tween the bars 25 25, so that the dies 19 and plug 22 arereleased from the finished bottleneck, when such neck can be withdrawn,another unfinished neck inserted over the plug 22, and the operationsrepeated.

In Fig. 6 there is shown another manner of attaching the plug-bars 25 25to the screwlug 29 in the shaft 3 by having said bars liinged or pivotedto the head 29 on said screw-plug 29, as at 29 so that said bars can beswung from said head 29 to open and close the sections 23 of the plug22, and in such case the springs 34 can be dispensed with. In Figs. 7and 8 the sections 23 of the lug 22 are shown as fluted throughout theirl ength, as at 22, in order to lessen the friction of such plug, and inFig. 9 the dies 19 are shown as provided with the springs 19 within theseats 20 for bearing against said dies, in which case bolts 21 can passloosely through the jaws into said dies and be held by nuts 21 in theends of the same. This will allow the dies 19 to expand and make theneck of the bottle always uniform. These and various other modificationsand changes in the construction and design of our improved machine forfinishing bottle-necks may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages.
